These tools can dump non standard sector with Bad CRC.
Of course a few of games dumped by these can't be restore to disks.
Because FDC for PC doesn't allow to make (write) Bad CRC to diskette.
(In this case, Trans Copy Option Board needs.)
Many of copy protected software checks any value in sector with logical Bad CRC via INT-13 function.

This is definitely interesting! Lemmings 2 is one of the examples which simply can't be dumped with the regular tools, I believe.

Would you consider donating your dumps to our collection? I see you uploaded two games, but since your list is quite extensive, we could also arrange direct FTP access to avoid the overhead of manual browser-based uploading.

Yes, I can upload a few of games.
If you show me FTP account, thanks.

P.S. I've checked sha1 for Gunship 2000 (Scenario disk)
It seems to be not dumped correctly.

Thanks, we have some images made with winimage that include that. I'm told that with the correct options that doesn't happen, but the people who make that mistake usually don't know (or don't want to know) how to use other programs.

I'll try to take a look as soon as I can, but it may take some time right now I fear.
